itest: set universe.disable-supply-verifier-chain-watch flag

Update the universe server integration test harness to set the
`universe.disable-supply-verifier-chain-watch` config flag.

This ensures that tests exercise the correct runtime behavior of
universe servers, which should verify only peer-submitted supply
commitments rather than monitoring on-chain spends.
